I have a pair of mildly ported E7 cylinder heads that I'd like to get rid of. Manley stainless steel valves, viton valve seals, comp springs and retainers. Machine shop gave them a 3 angle valve job and set up the springs for an F303 cam. Surfaced .005 and only 1,500 miles on them. No cracks or stripped threads. $200 firm. The valves alone cost more than that.
